How are euglenoids similar to animal-like protists?
They are both heterotrophs.
Does an euglena have a cell wall?
No, euglenas do not have a cell wall. They have a flexible pellicle, which is a protein layer that provides structure and support to their cell membrane. This allows for their unique ability to change shape.
What is the structure of a euglena?
The Euglena do not have a cell wall. What they have instead is a pellicle. The pellicle is what allows the shape to change.
What is a stiff layer of nonliving materials that surrounds a plant cell?
This layer is called a cell wall,
What is the main taxonomic group to which Euglena belongs?
Euglenoids are flagellates, single celled organisms in the Kingdom Protista. Euglenoids belong to the domain eukarya. It doesn't have a cell wall but a protein coat. It as a paramylon carbohydrate reserve. There are 900 species. And it is found in fresh water, polluted and estuary habitats.
What does the pellicle do in a protist?
In protists, a pellicle is a protein layer located beneath the cell membrane. It provides structural support and helps maintain cell shape. The pellicle also allows for flexibility and movement in certain protists.

What characteristic of the pellicle makes Euglena different from true plants?
The pellicle of Euglena is made of protein strips, providing flexibility and enabling movement, while true plants have a cell wall made of cellulose. This allows Euglena to exhibit more animal-like movement, such as swimming and changing shape.

Do paramecium have cell walls?
Paramecium is single celled.
Do Euglenas have cell wall composed of silica and shaped like the two sides of a pill box?
Euglena lacks a cell wall (an outer membrane containing cellulose). Instead, it has apellicle made up of a protein layer supported by a substructure of microtubules, arranged in strips spiraling around the cell. The action of these pellicle strips sliding over one another gives Euglena its exceptional flexibility and contractility.[11]
Do protists have cell walls?
There is no longer a Kingdom of Protists. They are not a monophyletic group (clade). So, the answer is some do some don't. Algae (a type of photosynthetic protist) tend to have a cell wall. Protozoa (the animal like protists) do not. Most single cell protozoa have a pellicle to protect the cell.
Is the cell wall considered an organelle?
No, the cell wall is not considered an organelle. It is a rigid structure found in plant cells and some other organisms that provides support and protection. Organelles are membrane-bound structures within a cell that have specific functions.

Why is cell wall said to be a dead component of the cell?
The cell wall is considered a dead component because it lacks the ability to actively respond to stimuli or grow. Once the cell wall is fully formed, it remains relatively static and does not undergo the same metabolic processes as the living components of the cell. It serves mainly as a structural support for the cell.
